An '''anode''' is an electrode
through which conventional current
flows into a polarized electrical device. A common mnemonic
is ACID for "anode current into device".
[Denker, John (2004) [http://www.av8n.com/physics/anode-cathode.htm#sec-def How to Define Anode and Cathode]. av8n.com ]
The direction of (positive) electric current is opposite to the direction of electron flow: (negatively charged) electrons flow out the anode to the outside circuit.
